Ymachine 0I" this Vcharacter isV performed fupon r.

1 serial 62914; j r

here@ the front truck that a threefold object is accomplished. First, as before stated, the weightis equally distributed upon the driv- "ing wheels of the truck so that the most effective traction is ,secured duringthe slow and powerfuly forward Afeeding movement .imparted to said driving wheels during theV vsumping operation.

Second, the weight of the forward end or nose of the gathering conveyor and the load thereon is` in a measure counterbalan'ced'withthe result that the friction between the nose of the gathering` 'Y conveyor and the mine fioor is largely i'elao i ve 'orswinfr throiwhout the varvinov ano'ub D u C Z:

lar 'positions of theseveral elements with respect to each other.

It is affurther object of the invention to provide a machine of the character indicated in which the discharge vend of the gathering conveyor is disposed within and below the level of the top of the sides of the hopper of the loading conveyor or elevator so that no coal may be thrown by centrifugal force bev yondthe hopper, and in conjunction therewith to provide movable panels at the upper front corners of the hopper adapted to be moved to permit the gathering conveyor to swing to a sharp angle with respect to the hopper without interference' from the walls thereof and adapted to be moved into posivtion to 'close the spaces that would otherwisejbe left when 'the gathering conveyor swings in the opposite direction and through elevation fof the coal bringing it to a `from which it may be discharged gravitally into: a mine ca r and the projectionV of the which spaces coal would be thrown by cen trifugalforce ifsuch panels were not provided [and the invention further contemi plates the .provision of means for automatically Vshifting said panels to proper position as the and forth. Y. y

A furtherobj ect of the invention is to provide an improved form of hopper and loading `'conveyor-'by which the coal will be both elevated and Y conducted rearwardly, the point gathering conveyor swings 'back conveyor rearwardly'providing such overhang as to permit amine car to be moved back ,and forthunder the discharge end of v the loading conveyor in such manner as to effectuallydistribute the load within the V mine car. Y

It is a further object of the'invention to provide in a structure embodying the several advantages liereinbefore set forth, mechanisms so shaped and related that the resultant loading machine, while beingvstrong, rigid, powerful and highly flexible, will be of minimum height and adapted to operate in mines having but little overhead room and inmines where a large part of the loading is done on comparatively sharp curves.

After this load is once started, the work of completing the loading ofthe pile is comparatively easy. The star*- ing of the Vload presents the most difficulty and the clutch construction just described provides means whereby the operator may,-

without injury to the mechanism, impart what is, in effect, a succession of blows to the pile of coal to start the same moving. This is accomplishedrby starting and stoppingthe ymotor 48 through the usual and well known controlling means of devices of that nature. The axis of the pin 64 is coincident with the axisy of a stud 71 which depends from the und-er side of the plate Q0 of the pan and has its bearing in the eye v19. An arcuate angle v'72 is-secured to theunder side of the plate 20' and comprises a horizontal flange 7 3 which projects beneath extensions 7 4 of a plurality of clips secured upon the top of the saddle ,casting 13 and this structure in conjunction with the stud 71 and eye 19 yconstitutes the connection between the gathering conveyor and the truck.

; At 76 we have illustrated, in a general way, a pony truck construction upon which the forward `part of the gatherino` conveyoris supported in elevated position and free of the mine floor during the time that the lloading machine is being transported about the mine.

A motor 77 provides means for imparting a rapid traveling movement to the truck for i conveying the machine about the mine or for imparting a relatively slow and powerful forl ward. movement to theltruck when forcing the nose end of the gathering conveyor into a Y pile of material to be loaded or for swinging the gathering conveyorback and forth across the mine floor andthe comiections are such that this swinging movement of the conveyor may belaccompanied by the slow forward movement so that the nose of the gatheringv i conveyor is cause-d to move obliquely into the pile of coal whensuch movement is lbest adapted to load the coal with the greatest speed.- rl`hisY slow positive forward movement vis known inthe art as a sumping movement. The motor is provided with brackets 78 Ywhich embrace the rear shaft 9 and with brackets 79 which restA between springs 80, which are in turn carried by rods Sl supported from the side frame members 5.

This construction provides al desirable yielding mountino' for the motor. Supported by the bearing lbrackets 82 from the casing of the motor is a back gear shaft 83, this shaft being driven by a chain 84, sprocket 85 from the motor. A sprocket wheel 86 that is fast upon the shaft 83 is connected by a sprocket chain 87 with a sprocket wheel 88 that is loosely mounted upon the axle 9. A clutch block 89 is splined at 90 upon the axle 9 and when this clutch blocln is moved to cause it to engage with clutch jaws 91 formed upon the sprocket 38, motion is imparted to the axle 9 and to the wheels 11 at a comparatively high rate of speed. This constitutes the traveling feed of the machine or the feed by which the machine is caused to travel at a comparatively rapid rate about the mine. The axle 9 is connected by means of sprockets 92 and 93 and a sprocket chain 94 with the axle 8 so that all four of the wheels 10 and 11 are driven in unison whether the rate of feed be at the traveling iate orat the sumping iu rate. A

Sprocket wheels 95 and 96 are mounted to turn loosely upon the back gear shaft 33 and these sprocket wheels are provided with clutch faces 97 and 93 adapted to be engaged by corresponding clutch faces upon clutch blocks 99 and 1007 these clutch blocks being splined upon the shaft 83. Means hereinafter described are provided for shifting these clutch blocks in unison toward and from each other so that both of the sprocket wheels 95 and 96 will be simultaneously forced into or out of action. These sprocket wheels ar-e connected by sprocket chains 101 and 102 with the sprocket wheels 103 and 104 that are fixed upon a shaft 105 that is journaled in bearings 106 of a worm gear casing 107. The shaft 105 carries a beveled gear 108 that meshes with a corresponding beveled gear 109 that is fast upon a shaft 110. This shaft carries a worm 111 that meshes with a worm wheel 11il that is fixed upon and imparts motion to a sleeve 113 which extends substantially the full length of the axle V8 between the wheels 10. `It is apparent that whenever through the medium of the Vclutch connections described, motion is imparted from the back gear shaft to the sprockets 95 and 96,

this motion will be transmitted to the sleeve wheels 10, it being apparent that when thisv is donc, a slow and powerful turning action will be imparted to the wheel and, through the axle upon which it is mounted and through the connections described to all of the other driving wheels to impart a powerful forward feeding action to the machine for the purpose of sumping in.
